Killua - HxH . Glass Chamber (Pixiv Fanbox)

Trapped in narrow glass chamber and fully naked, Killua struggle try not to press his penis againt the cold glass too much but his young and full energy testical still stuck between his thigh and the glass, the moving make his nipple press on the glass surface more and more .

On top of the chamber a device starts running and release a thick gas, it wont take long in the airtight design chamber for the gas spreading complete. Killua start to lose his mind due to the gas, an weird and strong erection turn his cute soft penis to a rock hard dick so fast it hit on the glass of the chamber, the penis he so worry about is now a fully erect boner .

Despite not able to move his hip much in the small space while his dick press againt glass and his belly make it unable to grab with hand either, but Killua had become so sensitive he can cum with just a small amount of movements, his hard red nipples start lactating and more white stuff start dripping down and fill the chamber .
